Willow, a female Rocky Mountain goat, died suddenly Wednesday at the Denver Zoo.

Animal care and health team members found Willow “experiencing a medical emergency” while she was miscarrying and she later died despite an hours-long effort to save her, the zoo said on Twitter.

Willow, and two other mountain goats among the zoo’s band, were born in 2019 in Tacoma, Wash., according to the zoo. The trio from Washington was “rescued after being declared ‘nuisance’ wildlife as a result of human-wildlife conflict in the area.”

The goats were moved to the Denver Zoo in 2020 and “quickly became beloved members of our animal family.”

Willow’s zoo care team described her as feisty, curious and beautiful.

“There will be one less pair of eyes inquisitively watching over the Zoo from the top of Goat Mountain and Willow will be dearly missed by guests, staff and volunteers.”
